DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite container (bag-in-box) in which an outer bag made of a plastic film with a spout for accommodating a liquid such as sake, soy sauce or a detergent is housed in an outer box made of paperboard or the like. In general), especially for the storage and storage of large volume liquids.
It relates to improvement of transport containers.

2. Description of the Related Art Conventionally, polypropylene resin (P) has been used as a container for storing various beverages, seasonings, liquid detergents and the like.
Plastic containers such as P), polyethylene terephthalate resin (PET) or polyvinyl chloride resin (PVC) are widely used.

However, in recent years, the increase in waste has become a major social problem, and in addition to the problem of resource protection and energy and resource conservation, it has become a global environmental problem. It is rare. As a countermeasure, a composite container (bag-in-box) in which a plastic film bag-like container with a spout is housed inside an outer box made of cardboard such as paperboard or cardboard is widely used. This container is lightweight and can be transported easily because it can be folded small when no contents are stored.In addition, the container can be reduced in volume at the time of disposal, and paper and plastic can be easily separated. These are environmentally friendly (ecological) liquid containers that can be recycled individually.

Conventionally, in such a composite container (bag-in-box), a large-capacity container for liquid, in particular, does not have a handle portion, and conveys and pours out the liquid during use. You had to lift the outer box with both hands. In particular, when the liquid is poured out from the spout, it is difficult to hold the liquid with one hand or the like, and the spout is unstable and difficult to adjust to the position of the container or the like, and it is difficult to maintain the pouring state.

Heretofore, there has been no liquid container, particularly a large-capacity container, provided with a handle so that the liquid can be easily poured. For example, as proposed in Japanese Utility Model Laid-Open Publication No. Sho 57-144840, a handle, a liquid spout and a liquid-impermeable membrane are united and joined together in a tightly closed shape along the outer periphery except for the spout. Although there was a liquid container as described above, this container was a small-capacity container, and the purpose of this handle was also to hold the liquid container by hanging it on a hook or the like. .

[0006] For example, as proposed in Japanese Utility Model Application Laid-Open No. Sho 62-87038, a part of a thermal bonding portion on the outer periphery of a synthetic resin packaging bag formed by heat-sealing the outer periphery is formed through a through hole. This is a packaging bag with a handle portion formed with a handle portion, which is a container consisting of a buffer portion provided with an unadhered portion or a cutout on the inner peripheral edge of the handle portion, and this container is also a small-capacity container. There was no spout, etc., and the handle was easy to pick.

Further, a composite container (bag,
In box), for example,
As proposed in Japanese Patent Publication No. 0, a take-out opening large enough to easily take out the spout in the inner bag by a perforation is provided on one surface of the outer box, and when used, the perforation is broken to take out the spout. After that, the broken piece was inserted again to support the spout and engaged.However, this container is not particularly gripped, and is used for transporting and discharging liquid during use. Was unstable and difficult to pour out.

In a composite container (bag-in-box) having a large content, for example, Japanese Utility Model Publication No. Sho 56-4
As proposed in Japanese Patent Publication No. 2202, a carrying box, at least one carrying hole provided through the side wall from the inside to the outside of the box, and the carrying handle, An outlet having an engagement portion with which the spout of the inner bag is engaged continuously below the hole.
That is, at least one handle hole is provided on the side surface of the outer box, which is useful for transportation or the like. However, the handle hole is unstable and difficult to discharge liquid. Met.

As described above, in a conventional bag-in-box, particularly a large-capacity one for liquids, there is no useful handle, and the outer case is used for transportation during use and for pouring liquids as contents. Had to be lifted with both hands. In particular, when pouring the liquid from the spout, it is difficult to hold, and the spout is unstable and difficult to adjust to the position of the receiving portion, etc.,
In addition, there is a problem that it is difficult to maintain the pouring state.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings. The liquid storage and transport container of the present invention,
For example, as shown in FIG. 1 (a), a protrusion-like handle (24a) having a spout (6) and a cut (24a) in an extension of the top surface seal portion (22) is provided on the top surface of the inner bag (20). 24) is housed in an outer box (10) shown in FIG. 1 (b), and is attached to a top flap (16) on the top of the outer box (10). A handle take-out piece (A) and a spout take-out take-out piece (B) are provided at positions corresponding to the spout (6) and the handle (24) of the inner bag (20) by means of perforations (h). It is characterized by holding.

More specifically, in the outer box (10), for example, as shown in FIG. 2, a glue strip (11), a rear plate (12), a right side plate (13), a front plate (14) and the left side plate (15) are connected in this order, and then the top and bottom flaps (17) having a spout and a handle takeout hole (C) at the upper and lower ends of the rear plate (12) through crease lines. Flap (18), right side plate (13)
Spout take-out strip (B) at the upper and lower ends of the crease line
Top flap (16) and bottom flap (1
8), and a lower flap (17) and a bottom flap (18) provided with a spout and a hole (C) for taking out a handle through upper and lower fold lines at the upper and lower ends of the front plate (14).
5) A blank (2) in which an upper flap (16) having a handle take-out piece (A) at the upper and lower ends via a fold line and a bottom flap (18) are connected as shown in FIG. When the upper flap (16) is opened, the spout and the handle take-out hole (C) appear at substantially the center of the lower flap (17).

The outer case blank (2) in the above case is made of corrugated cardboard and has a relatively large capacity, but in the case of a relatively small outer case (10), the top surface is formed from a single lid plate. In such a case, the spout and the hole (C) for removing the handle are unnecessary, and the form of the top flap (16) is also different. The form of the blank (2) is not particularly limited. No, a handle removal piece (A) on the top
And the spout take-out piece (B) may be held by the perforation (h).

As shown in FIG. 1 (c), when the liquid storage / transport container obtained above is used, the handle take-out piece (A) and the spout take-out piece (B) are perforated (h). To form a spout hole for the spout (6) and a handle take-out hole for the handle (24), which are provided on the top surface of the inner bag (20) from the formed holes. Pull out the handle (24) and the spout (6), and pull the handle (24).
In the notch (24a) so that it can be carried easily and with one hand.

Further, as shown in FIG. 1 (d), when pouring out the liquid as the contents, the plug of the spout (6) is removed, and a handle provided on the top surface of the inner bag (20) with one hand. (24) The liquid can be stably and easily poured out while holding the bottom of the container or the like with the other hand and tilting.

As described above, the handle (24) and the spout are taken out of the holes of the handle (A) and the spout (B) provided on the top surface of the outer box (10). Since the handle (6) is taken out, the width of the projection-like handle (24) is preferably smaller than the width of the handle take-out piece (A) as shown in FIG. Therefore, it may be large. Also, the width of the handle (24) on the protrusion is equal to the inner bag (2
Desirably, the value is considerably smaller than the width of the top surface sealing portion (22) of 0). This is not impossible even with a protruding handle (24) having the same width as the top surface seal portion (22) as an extension of the top surface seal portion (22). This is because the outer flap (16) must be provided so as to cover the entire width of the upper flap (16).

[0018]

As described above, the present invention has the following effects. That is, a plastic film inner bag provided with a spout and a protruding handle having a cut on the top surface is stored in a cardboard outer box (back-in-box). On the surface, a handle removal piece and a spout removal piece are provided at positions corresponding to the spout and handle of the inner bag, so that when using this liquid storage / transport container, the handle removal piece and the spout are used. The outlet take-out piece is torn in accordance with the perforation, the handle provided on the top surface of the inner bag and the spout are pulled out, and the cut of the handle is hung so that it can be easily carried with one hand.

Furthermore, when pouring out the liquid as the contents, take off the plug of the spout, hold the handle with one hand, and tilt the container with the other hand while holding the bottom of the container or the like. It can be dispensed.
